` Speciicat'ion e! Letters Iatent.

- ,Be it known that I, MAxEPsTEIm-'a' citizen of -the United States, residing at Chi-v cago, in the county of Cook and StateOf l Illinois, `have' invented" new Aand, useful Improvements in Tank-Cars, of whclitheffollowingis-a specication'.- My invention relates to'certain new and useful improvements i-ni'a tank-car, and is fully described and explained in the specifi` ,cation landv shown in drawings, in which Figure vl is a side' elevation of myl im- .provedwcar;Fig. 2' is a section-in the line 2 Fig. '2 of a modified form ofcnstruction.

In the past considerable diiiicultyhas-been experienced in connection with tank-cars, in

properly securing 'the t'ankto: the car-body 1n -sucha way 4as to secure a perfectly firm support-and still not-subject the tank, or lany part thereof, to undue 4strain under. 'opera-' tive conditions. Such strains may be caused bythe momentum df the .tank under .sudden shocks tothe-carbody and moreespel' cially by tendencies to displacement caused bythe movement the'tank.' *In devising means for attachmgtihegtank toj-the bodyoiI thecar, .it'is notV only A'de-A sirabie that the, ank be .firmly attached vto 35' the body in such a manner not to be strained-'underthe'shocksoccurring in prac `tice,'lout;thz it'the attachment -be one whlch 4'can be released'without too great difficulty,

soy that `in case ofn'ecessary repairs 4the tank.

can .belifted from the body by f a crane andconveniently operatedufion.

The tankfcar here illustrated `has many features in commonv with ltankcars as now ordinarily made, butit is so designed as to'4 `incorporate a no velmethod of attaching the tank to the vcar-bod'yto secure the 4foregoing results.

Referring now to the, drawings, A is one ofthe body-holsters, the ,two body-holsters carrying between' .them and supported by' .themtwo longitudinally-extending and outi wardly-facing channelfhea'ms B .constituting centersills.-

These clips are centrally perfo--Y rated and receive the fli'oltsGby .lneansof .which they'niay be pulled tightly togetlieri In this manner a very rni'andrigi'd attachnient is provided for Cthe-,tankaudj yetfone which will permit justenough nioticnftd .relieve the strainl of eXp'a1'1'sion.-and contrae; --tion or. any other extraordinaryA straim and which connection -can very quickly be dischgaged to per-mit the tank togbefrelnored from f ,the car-body.V vThe beams D attachedftothe tank run' over a largefpart iof thefllength thereof and'c'anbe so firnilyfrirete'clgastobe practically a partv of tlr'e .tank;. ,itsel f Fur thermore', the beams Df-:theinselVQS-gal??
